TECHNOLOGICAL FIELD

The presently disclosed subject matter is in the field of structure assembling. According to a first of its aspects, the disclosure is concerned with a panel fastening system for a structure. According to a second aspect of the disclosure there is a modular door system and a method for its assembly. According to yet an aspect there is disclosed a corner coupler for a structure.

BACKGROUND

Construction assembly of different structures, such as garden cabins, partition walls, fences and the like, has become very common at the DIY market.

An important consideration among DIY manufactures is modularity of components, i.e. the ability to manufacture as little components as possible, however suitable to serve for different purposes. This has an important weight in the overall manufacturing costs.

Yet an important consideration is the provision of easy to assemble components, requiring minimal use of tools, minimal force and only little professional knowledge.

These, along with other criteria, such as light weight components, durability and environmental considerations, such as use of recycled material, render certain products to be desired over other products in the same market.

GENERAL DESCRIPTION

According to a first of its aspects, the present disclosed subject matter calls for an artificial panel of material for use in the assembly of constructions. Such panels are required to be fixed in a tight fashion to a support structure, or required to be attached thereto to various elements such as shelves and the like, typically by fasteners. It is desired to render fastening of such panels in an easy manner, i.e. fast and easy, yet in a sturdy manner.

The term artificial panel as used herein in the specification and claims denotes a panel of material made of molded or extruded material such as different plastic materials. According to one particular embodiment, the panel is made of WPC (a common abbreviation for ‘Wood Plastic Composite’).

An artificial panel constructed from the above-mentioned materials is considered inferior in strength compared to traditional construction materials such as wood or metal and can also be ductile. Moreover, such materials are often brittle.

An artificial panel according to the first aspect of the disclosure is configured with a spaced apart first wall and second wall, each wall defining an inside surface and an outside surface, and at least one fastener location configured at an outside surface of the panel, for receiving therethrough a fastener.

The term fastener as used herein in the specification and claims denotes a screw (e.g. self-threading or regular, a blind rivet, and the like).

The location configured for receiving a fastener is designed to overcome the artificial material inferiority in strength, ductillness, and brittlness compared to traditional construction materials.

DETAILED DESCRIPTION OF EMBODIMENTS

Attention is first directed to FIGS. 1 and 2 of the drawings, illustrating a cabin generally designated 20, comprising walls 25 (front, rear and side walls), all made of horizontally disposed panels, said panels generally designated 30. The cabin further comprises a front door composed of a right wing door 40R and a left wing door 40L, roof 48, a floor 50 and other elements not seen in FIG. 1

As mentioned, and as can best be seen in FIGS. 3A and 3B, the panels 30 are horizontally disposed. The panels 30 are made of molded or extruded material, such as plastic materials, WPC (Wood Plastic Composite), etc., with a variety of additives possibly added thereto, e.g. color, UV repellent, etc. Each panel 30 comprises a first (inside surface) wall 60 and a parallely disposed, spaced apart, second (outside surface) wall 62. Each of the panels 30 is formed at its inside face 60, with a plurality of fastener locations designated 68, for receiving a fastener therethrough (FIG. 4B) and securing the panel 30 to a support member such as a beam (mullion/muntin) 70, or for mounting to the panel an article, such a shelf, picture and the like (not shown). FIGS. 4A and 4B make particular reference to different examples of fastener locations.

It is further seen that the horizontally disposed panels 30 are configured with male-female engaging elongate edges 74 and 76, respectively (best seen in FIG. 4A).

The panels 30 have a smooth, flat inside surface 60, whilst the outside surface 62 is formed with a longitudinally extending groove 78 (FIGS. 3B and 4A) imparting a single panel 30 with the appearance of several panels articulated to one another. Likewise, the male-female engaging elongate edges 74 and 76, respectively provide tight and water resistant attaching of neighboring panels 30, yet with an eye pleasing gap (nonfunctional), and extending at a fixed vertical distance, with some overlapping between mating edges of neighboring panels.

Different aesthetic features can be imparted to the panels, such colors and patterns and likewise, the panels can be or comprise translucent (see through or light-passing) portions. Also, the panels 30 can comprise venting grids 80, widows 82 (fixed or openable).

Turning now to FIGS. 4A and 4B particular examples of fastener locations are illustrated and exemplified. In the present examples the illustrated fastener is a self-screw 94 (e.g. self-tapping screw), though it is appreciated that other types of fasteners can be used, such as other types of screws and blind rivets.

Detail ‘A’ in FIGS. 4A and 4B is directed to a fastener location designated 90, wherein a thickened wall portion 92 is provided at the inside surface of inside wall 60 of the panel 30, with a self-screw 94 threaded directly into the fastener location 90 and projecting into the internal space 96 of the panel. If desired, a noticeable mark can be applied on the surface of the panel (not shown, however such a mark can be a slight groove similar to that illustrated in connection with detail ‘D’ discussed hereinafter, or an indentation (not shown), such a visible mark can serve for easy identifying the locations of the fastener location and for eye-pleasing equi-distant applying of fasteners.

Detail ‘B’ in FIGS. 4A and 4B is directed to a fastener location designated 100 which is a narrow gap between two neighboring ribs 102A and 102B. the gap 100 can be a bore open at the inside surface of wall 60 of the panel, or it can be filled with a soft material, such as a resin and the like, for eye pleasing, i.e. such that unused fastener locations are not open bores seen at the inside of the panel. Screw is screwed and retained within the tight gap 100. It will be appreciated that the gap can be nonexistent such that the rib is substantially solid, made from the same material as the remainder of the panel.

Detail ‘C’ in FIGS. 4A and 4B is directed to a fastener location designated 110 wherein a rib 112 is disposed parallely between inside wall 60 and outside wall 62, and where a self-screw 94 is threaded directly into the fastener location 110 and penetrates through both the wall 60 and the rib 112, projecting into the internal space 114 of the panel.

If desired, a noticeable mark can be applied on the surface of the panel (not shown), however such a mark can be a slight groove or notch similar to that illustrated in connection with detail ‘D’ discussed hereinafter, or an indention (not shown). Such a visible mark can serve for easy identifying the locations of the fastener location and for eye-pleasing equi-distant applying of fasteners. It will be appreciated that the mark can also be an outwardly protruding element.

Detail ‘D’ in FIGS. 4A and 4B is directed to a fastener location designated 120 in the form of a longitudinal groove 122 extending through the panel 30 between two parallel ribs 124A and 124B and with a groove or indention 126 formed at the inside face of inside wall 60, for identification and easy location of the fastener location 120, such that a self-screw 94 can easily be threaded into the fastener location 120.

FIGS. 4C and 4D illustrate another example of the fastener location designated 120′ (same elements are designated using same numerals as in connection with the previous example, while elements having different configuration, are marked with “′” following the numeral). Detail ‘E’ in FIGS. 4C and 4D is directed to a fastener location designated 100′ which is in the form of a solid conical rib extending between the two opposite walls 60 and 62. It will be appreciated that the central longitudinal axis of the rib, is perpendicular to the walls 60 and 62. As in the previous example, the outer face of the inner wall 60 comprises a groove or indention 126′, for identification and easy location of the fastener location 100′, such that a self-screw 94 can easily be threaded into the fastener location 100′.

The fastener location in the form of a conical rib 100′ is comprised in accordance with this example of a conical solid portion 121 and a narrower extension rib 123 connecting the conical portion to the inside surface of the outer wall 62, such that the fastening element, e.g. a screw as seen in FIG. 4D, extends substantially therethrough. It will be appreciated that the screw can be screwed into the conical portion 121 only. This structure allows having a solid fastening location for tight threading, while the outer wall 62 of the panel is not affected by sink marks, which might result from fastener locations having a broader rib portion connecting to the outer wall 62 of the panel 30. This maintains an eye-pleasing surface on the outer wall, without giving a hint to the presence of the rib and the screw threaded therethrough. In addition, such a configuration allows economy in the plastic material used for the panel. The screw in accordance with an example of the disclosed subject matter can at least partially outwardly extend (e.g. its threads) beyond outer surface of the rib, thus to a certain degree resembling the function of the masonry anchor. It will be appreciated that the conical portion of the rib can be provided with a bore, e.g. filled with a soft material.

As seen in any one of the details described hereinabove, the screw does not require a fastening bolt and yet it does not penetrate through an external face of the panel, however without deteriorating fastening/gripping force of the bolt to the panel. The screw screws into the rib and is maintained securely in its position without unintentional falling out, or causing any damage to the outer surface such as cracks which might appear due to the type of the material used which is often brittle when compared with other materials. In particular, with panels having relatively thin walls which might be needed due to weight considerations or material saving considerations, it will be a tendency of a composite material for example such as WPC to exhibit fragility/brittleness when screwed into. Provision of the fastening locations in accordance with the disclosed subject matter allows reducing and preventing such unintentional defects.

It is appreciated that the provision of air voids in the panel improved its thermal and noise isolation properties, and further, that the provision of support ribs improved rigidity of the panels.

Attention is now directed to FIGS. 5 to 9 directed to a second aspect of the present disclosure, concerned with a modular door.

The cabin 20 is configured at its front wall with a right door 40R and a left door 40L (also seen in FIG. 1). As will become apparent hereinafter, the two doors 40R and 40L are composed of same components, rendering the system modularity, simplicity and cost effective.

Each of the door systems comprises a main body 200 made of molded plastic or WPC material and configured with an outside face 204, an inside face 208 bounded between a first (top) edge rail-mount 210 and a second (bottom) edge rail-mount 212, a hinge stile 216 and a locking stile 218.

Snapingly articulated within the first (top) edge rail-mount 210 there is received a first (top) rail 222 and likewise, a second (bottom) rail 224 is snapingly articulated within the first (top) edge rail-mount 210. Each of the first rail 222 and the second rail 224 is fitted with a projecting hinge portion 226 (best seen in FIG. 7A) and configured for rotatably receiving within a door bushing 228 of the door jamb 230.

According to a particular configuration, the first (top) rail 222 and the second (bottom) rail 224 are identical and are configured for interchangingly articulating within either the respective first (top) edge rail-mount 210 and the second (bottom) edge rail-mount 212. However, in such a configuration the projecting hinge portion is configurable for respective projecting upwards or downwards such that after mounting on the respective top or bottom edge it projects from the door. This can be obtained by a fixed hinge projection extending at both sides of the rail, or for example by a hinge projection displaceably mounted between a top projection configuration and a bottom projecting configuration, respectively.

As seen in the figures, the main body 200 is configured with a central portion 234 in the form of solid sheet panel symmetrically extending between the hinge stile 216 and the locking stile 218 and between two venting grid portions 236A and 236B and further, two window portions 238A and 238B. The central solid portion 234 is configured at its front face 204 with a plurality of reinforcing ribs 242 (longitudinal in the present example) projecting from the surface of the front surface. The back, inside face 208, is substantially flat though texturized with longitudinal grooves 246 so as to impart the central portion with a mating panel-like appearance.

The central portion 234 and the venting grid portions 236A and 236B are configured with a plurality of openings 250 and the front surface of the central portion 234 and the venting grid portions 236A and 236B are configured with a plurality of snap locations 254.

A cladding panel 260 is configured with a flat outside panel portion 262 (designed with a grid pattern for imparting a mating-like panel appearance), a translucent window portion 264 conforming as far as shape and size with the venting grid portions 236A and 236B, and a venting portion 266 conforming as far as shape and size with the window portion 238A and 238B. In the particular example the window portion 264 is an opening in the cladding panel, though according to a different example (not shown) the venting portion can be a grid-like portion.

An inside face of the panel portion 265 is configured with a plurality of coupling bolts 270 sized and spaced apart in register with the plurality of openings 250 configured at the main body 200, and a plurality of snapping members 274 extending in register with the plurality of snap locations 254 configured at the main body 200.

The cladding panel is mounted and secured to the outside face 204 of the main body 200 by snap articulation of the snapping members 274 of the cladding panel 260 to the snap locations 274 of the main body 200, and further by screws extending from the inside face 208 of the main body 200, through openings 250 and coupled to the bolts 270 of the cladding panel 260.

It is seen that the cladding panel can be articulated to the outside face 204 of the main body 200 at either an upright position (right side door configuration) or a bottoms up position of the main body 200 upon rotating at 180° in the plane of the door (arrowed line 213 in FIG. 9; left side door configuration), wherein the cladding panel 260 remains at an upright position as indicated by arrow 215, i.e. its orientation does not change while assembling a door at either orientation thereof.

In both a right side door orientation (FIG. 8) and a left side door orientation (FIG. 9) the cladding panel 260 covers (covers so as to conceal and render same nonfunctional) the respective bottom venting grid portion 236A and the respective, whilst the respective top venting grid portions 236B and the respective top window portion 238B remain functional, i.e. the top venting grid portion 236B of the main body extends in register with the window portion 264 of the cladding panel 260 and the top window portion 238B of the main body 200 extends in register with the translucent window portion 264 of the cladding panel 260.

According to the disclosed arrangement, the door system disclosed hereinabove can be configured as either a right door configuration or a left door configuration, however using the same components, rendering the door system complete modularity.

It is appreciated that the door system can be configured with any one or both of the venting units and the window.

The door is further fitted with a locking system generally designated 280 comprising a lock, a lever and vertically displaceable locking latches (FIG. 7A).

It is also appreciated that while in the disclosure above the door system comprises a single cladding panel configured for articulation at a front face of the door (i.e. external face of a door), a cladding panel may also be applied at an inside face of the door and even more so, the cladding panel can be composed of several panel segments.

Further attention is now directed to FIGS. 10 to 13 of the drawings, directed to a third aspect of the present disclosure, concerned with a corner coupler configured for coupling two wall members.

As seen in FIGS. 2A and 2B, and better so in FIG. 10, the cabin 20 has wall members designated 25A (back wall of the cabin 20) and 25B (right side wall of the cabin 20) articulated at a corner of the cabin through a corner coupler generally designated 300.

As can be seen in the drawings, the corner coupler 300 is generally a symmetric Ω-like shaped metal-sheet member, comprising a U-like shaped inter-wall gap support 304 from which extend a first wall support arm 308A and a second wall support arm 308B, both disposed at an angle α of at least 90° with respect to the inter-wall gap support 304. The first wall support arm 308A is configured at a free end thereof with a first wall gripping edge 310A, and the second wall support arm 308B is configured at a free end thereof with a second wall gripping edge 310B.

Whilst in the present disclosure the interconnecting portion 312 of the inter-wall gap support 304 is straight and disposed at 90° with respect to its side members 314A and 314B (parallely disposed), an arched configuration can be formed as well, concave or convex with respect to a bisector X symmetrically extending between the first wall support arm 308A and the second wall support arm 308B.

The first wall support arm 308A and the second wall support arm 308B as well as the interconnecting portion 312 of the inter-wall gap support 304 are configured with a plurality of openings 320. The openings formed at the first wall support arm 308A and the second wall support arm 308B are configured for coupling the corner coupler 300 to the wall members 25A and 25B, respectively, through a plurality of screws 325. Openings 320 at the interconnecting portion 312 of the inter-wall gap support 304 serve for securing an external cap profile 330 (represented in FIG. 11 by dashed lines) concealing an outside of the gap 311 (referred to as an ‘inter-wall gap’).

The arrangement is such that when the corner coupler 300 is mounted at a corner between two wall members 25A and 25B of the cabin 20, the inter-wall gap support 304 extends between facing chamfered edges 332A and 332B of the wall members 25A and 25B, respectively, with said chamfered edges 332A and 332B bearing against the side members 314A and 314B of the inter-wall gap support 304, and the first wall support arm 308A and the second wall support arm 308B bear against respective portions of the first wall member 25A and the second wall member 25B, with the first wall gripping edge 310A and the second wall gripping edge 310B bearing within a groove 27A and 27B (best seen in FIG. 11) of the wall member 25A and the second wall member 25B, respectively.

It is seen that in FIG. 11 the first wall support arm 308A and the second wall support arm 308B are slightly spaced apart from the respective wall members 25A and 25B, wherein the extent of fastening the screws 325 governs elasticity thereof. However, in the example of FIG. 13 first wall support arms bear flush against the respective wall members, as will be explained hereinafter.

FIG. 13 illustrates a corner coupler 350 similar to corner coupler 300 disclosed in FIGS. 10 to 12, however with some differences. In the embodiment illustrated in FIG. 13, the side members of the 352A and 352B of the inter-wall gap support 354 extend the full depth of the inter-wall gap 356, such that interconnecting portion 358 extends in-line with the external edges of the chamfered edges 332A and 332B of the wall members 25A and 25B, respectively.

Furthermore, first wall support arm 360A and the second wall support arm 360B are configured for flush bearing against the respective wall members 25A and 25B and securing thereto by screws (not shown) through openings 320. It is seen that the first wall gripping edge 370A and the second wall gripping edge 370B extend at the free ends of the first wall support arm 360A and the second wall support arm 360B, however via an intermediate, inwardly curved portion 374 imparting the wall support arms resiliency for spring biasing into the respective grooves 27A and 27B of the wall members 25A and 25B.
